Our Verdict
Gigabyte M27Q (rev. 2.0)
Samsung Odyssey G50D S27DG50
The Gigabyte M27Q (rev. 2.0) and the Samsung Odyssey G50D S27DG50 are both budget-friendly 1440p gaming monitors. They're similar for the most part, but the Samsung model has a few advantages. For example, it gets brighter, which is something to consider if you want to use this model in a bright room. The Samsung also has much better motion handling with fast-moving objects. On the other hand, the Gigabyte has a few extra features, like the fact that it has a USB-C port and a KVM switch, which helps if you want to connect different computers to it.
